VSCode's webview doesn't reliably play VP9/WebM, while JetBrains'
JCEF lacks H.264 decoding. Restore the original H.264/MP4 video and
use HTML5 <source> elements with explicit MIME types so each platform
picks the format it supports:
<source src=... type="video/mp4" /> <!-- VSCode -->
<source src=... type="video/webm" /> <!-- JetBrains -->
Also:
- Restore .mp4 Git LFS tracking in .gitattributes
- Update CI LFS verification to check both files
- Add webm to JetBrains MIME type map (BrowserRequestHandler)
JetBrains IDEs use JCEF (Chromium Embedded Framework) for webviews,
which often does not include H.264 decoding due to licensing
restrictions. This causes the kanban demo video to fail to play.
Transcode the video from H.264/MP4 to VP9/WebM, which is a royalty-free
codec universally supported in Chromium derivatives. This also reduces
the file size from 3.6MB to ~900KB.
Updated all references:
- Source component import (ClineKanbanLaunchModal.tsx)
- Git LFS tracking (.gitattributes)
- CI workflow LFS checks (publish.yml, publish-nightly.yml)
